For my biology lab I created a bar graph of the comparison of the Nitrogen level of water in lakes and rivers, and I just need help with these questions, I would really appreciate it. Sorry about the graph being sideways, I tried to fix it.

My question is why is the Nitrogen level higher in the lake than the river?

1. a. Why is it important to discuss water nutrients, relate this to your question?

b. What can you conclude?

c. What was missing, or what would be interesting to look at in the future? What else would be useful to know?

d. Thinking of sustainability, considering what you said was important, what could be done to make the area more sustainable? Why is it important to think about this question?
